The Grace drivers used to be very nicely made but the last set I ordered came in with every drivers tip having non parallel sides. I sent them back. I think they're importing them now from Asia. The Chapman sets are pretty good for the price. If you want to just start at the top of the line buy Brownells Magna set. I have a box full of bits from the hardware store that I ground to perfectly fit a screw and then never needed that size again. You'll get very good and custom fitting bits to your work. You will never have enough bits or the right size. There seems to be NO world standardization of screw slots. Huge +1 on the Law Enforcement handle. That's all I use anymore.
